He rejected the Liberals' claim to have a mandate to unwind the agreement.

Liberals forestry spokesman Peter Gutwein said he would not be "greenmailed".

"Threats by environmental groups that the Liberals plan to rip up the sham forestry deal will reignite protests will not sway a majority Liberal government from taking the action needed to rebuild our forest industry," Mr Gutwein said.

Labor has vowed to continue to implement the Tasmanian Forests Agreement. That is the key plank of the party's forestry policy unveiled yesterday at Ta Ann's Smithton mill.

Deputy Premier Bryan Green said a re-elected Labor government would also negotiate a new regional forest agreement with the Commonwealth.

The policy includes $5.8 million in new spending, including money for research into plantation products, $1.5 million to offset costs of transporting forest residues to Bell Bay, and more assistance for workers.

Mr Green said the Liberals had failed to provide a credible alternative.
